This invention relates to improvements in door operating and sealingmechanism, and more especially such a mechanism for slidable doors ofhouse cars.

One object of my invention is to provide an eflicient combined'dooropening, closing and locking mechanism for slidable doors which consistsof the minimum number of parts capable of carrying out the three func:

ti'ons indicated. I

Another object of my invention is to provide a mechanism of thecharacter indicated, such that, when the usual car sealing ribbon i hasbeen removed, the operator is enabled to 5 unlock the mechanism andimpart the initial opening movement to the door by a simple manipulationof a single actuating lever and without the necessity of otherwise usinghis hands.

More specifically, an object of my invention is to provide a mechanismfor the purpose described wherein are employed a hasp-link,

a hasp-staple' and an actuating lever so arranged that the hasp-link mayfirst be unlocked, then disengaged from its hasp-staple,

even when under heavy friction, and then.

actuated by manipulating the lever, to the end that the operation may befacilitated and speeded up.

- Other objects of my invention are to provide a mechanism of the typeindicated which is adapted for holding the door in a partially open or'ventilating position; to provide means whereby the actuating lever maybe locked when not in use, and the door in open position, whereby toprevent unrestrained swinging or flapping of the lever when the car isin motion.

In the drawings forming a part of this specification, Fig.1 is abrokenelevational view of portions of double doors of an automobile car,showing my improvements ap plied thereto, the doors being in fullyclosed position'andthe mechanism locked. Fig. 2 is a view similar toFig. 1, but illustrating the condition of the parts'when the door is inpartially open or ventilating position.

Fig. 5 is a horizontal sectional Viewcorresponding to the line 55 of Fig. 3. Fig. 6 v is a view similar toFig. 1 illustrating another embodiment of the invention. And Fig. 7 is avertical sectional view corresponding to the line 7-7 of Fig. 6. I

In said drawings, and referring first to the construction illustrated inFigs. 1 to 5, inclusive,.10 indicates the main door and 11 the auxiliarydoor of an automobile car and to which my improvements are applied. Asunderstood by those skilled in the art, the auxiliary door will belocked against slidable movement while the main door 10 is being openedor closed. In the embodiment chosen for illustration, the actuatinglever and lock are shown applied to the auxiliary door and the hasp-linkto the main door, but it will be understood by those skilled in the artthat this arrangement may be reversed and also that the improvements areequally adaptable to a house car or equivalent, having only a singledoor, and that the actuating lever and lock may be applied either to thefixed framework or to the movable door.

. Incarrying out my invention, I employ a hasp-link 12, an attachingplate 13 therefor, an actuating lever 14, an attaching plate or bracket15 therefor, and a locking arrangement, the details thereof beinghereinafter described. v

The doors 10 and 11 are of well known construction, of the sheet metaltype. The main door 10 is provided at its forward edge with i avertically extending corrugation 16 reinforced on the inner side thereofby a strip- 17 and outwardly of the corrugationthere is secured to theedge of the door a combined bracing and weather sealing bar 18. Mergingwith the vertical corrugations 16 are horizontal corrugations 19 and theattaching plate 13 is preferably so formed as to fit over one of thecorrugations 19 and riveted to the crest thereof. At the end of theplate 13 nearest the forward edge of the door, a loop section 20 isformed, havinga shouldered tip 21 hooked through the corrugation 16 andstrip 17, as best shown in Fig. 5. The hasplink 12 is loosely pivotallymounted on the loop section 20, to adapt the same for swingingvertically and horizontally with respect thereto.

The auxiliary-door 11 is constructedsimilarly to the door 10, said door11 having-averticallyextending corrugation 22, with a reinforcing strip23 th'erewithin and horizontal corrugations 24 merging with the verticalcorrugation 22. At its forward edge,v

the door 11 has a combined reinforcing and weather sealing bar 25, thelatter havinga forwardly and slightly outwardly inclined flange26"beneath'which seatsthe bar 18''of-th'e main door 101" The "attachingplate, or bracket- 15; for the I actuating; lever has one section 27thereof conformed and riveted to' the crest of: one of the" horizontalcorrugations 2.4 and has another vertically and forwardly extendedsection 28 conforming'and riveted to the vertical corrugation 22:. andthe flat marginal portion 29iof thedoorill', as best indicated in F ig;5; As :willlbe understood; the attach 'ingplatesor-brackets may bemodified so as to fit any particulardesign' of door to which applied;

The bracket 15, ini-line with the hasp-at taching plate 13,is'formedwith an outward ly extended lug 30, the same-being outwardlytaperedand having a recess 81 therein, thus providing a staple forthehasp or link 12, the latter having a suitable elongated opening 32 Itherein adapting the same to bet fitted over the staple orlug 30.

On the upwardly extended section 28 ofthe bracket 15is formed an.outstanding boss 33 and'integrally formed, with the latter is aslightlytapered journal 34, as best shown in Figs. and 5. Slidably; androtatably mounted onth-e journal 34-is a. loop-shaped hanger 37, thelatter being prevented from becoming disengaged by a washer 36overlappingtheside arms of the loop hanger-37,

said washer being secured by a rivet 3'5'pass-,

ingthrough the journal 34;

At its upper-end, the hanger 37"is provided with an upwardly projectingcentrally-- disposedjiange 38', to whichis pi-votally' connected, as byrivet =39 the upper looped" end 40 of the actuating lever 14'.-

The lever -l l is p-rovided with a relatively-.- elongated d'epenrli nghandle-41 and ia-lso has Said upper looped end40 is-so-formed 'astoreadily stra'ddle'or surround the loop hanger-37 so that the actuatinglever may be in either the pl-a-ne ofth'e-hanger or swungoutward-lytherefrom, I

integrally formed therewith, and laterally offset from the lower portionof the loop section 40, an arm 42 from which depends a finger or bolt 43adapted to enterthe o-pening 31 of the hasp lug 30. At the upper end ofthe finger 43 an outwardly extended shoulder44 is'formed, the samehaving an opening- -45- there hrough in alinement with the .thehasp-link disengaged frointhe lug without breaking the seal.

The link 12 is formed with an upwardly curved end section indicated at46,- within which is. formed an elorigated open1ng47 having a-restrictedmouthorentrance 48.

The opening-47" and the shoulders at the opposite ends formed thereby,are provided to cooperate with a heavy stud49 having afl'anged"l1ead"50, which is integral with the handle portion 41 of theactuating lever. It

The operationof the-improved mechanism is as follows, assuming that theparts are in lochedpositlo-n shown in Fig. .1. After the breaking of''theseal, the'lever 14 is pushed vertieallyto theposition shown inFig.3,

which removeszthe bolt'4'3 from the hasplug. Incidentally, itiwill benoted that the flanged. head 50 oft-he lug. 49 will engage under-the:

It willfurther be observed that the lever 14;

may beretained in its vertical position when 'mizing the danger ofbreakage of the lever when the car is in motion.

Referring next to the construction illustratedin Figs'G and 7, theattaching plate 113 and link 112 are the same as the two correspondingparts previously described.

. The plate or bracket 115 is similar to the plate 15 but is slightlymodified so as to provide a higher or deeper shelf 60 from' which isprojected outwa dlythe staple or hasp lug 130..

The actuating lever 114 is mopnted on the bracket 11 5 in the samemanner as the lever 14 except that the boss 33 of the first describedconstruction is omitted, hence bringing the lever in a normal planecloser to the door than in the first described construction. Thedifferences are for the purpose of positioning the lever 11 1 beneaththe link 112 and because of this change, the arm 142 on the lever isoutwardly as well as laterally offset, soas-to bring the locking fingeror bolt 143 in proper position with respect to the lug130. The stud 149of the lever is on the outer side because of the reversed position. ofthe link.

The operation of the construction just described is manifestly the sameas that first described, with the difference that the hasplink isdisengaged from its lug or-staple by the main partof the lever 114instead of by the flanged head of the stud, as in the first describedform. ,7
